What is the main difference between nightgoggles and thermal imaging nightgoggles?
1. In total darkness, thermal imaging night vision devices have obvious advantages
Since the thermal imaging night vision device is not affected by light, the viewing distance of the thermal imaging night vision device in total darkness and ordinary light is exactly the same. Second-generation night vision devices and above must use an auxiliary infrared light source in total darkness, and the distance of the auxiliary infrared light source can generally only reach 100 meters. Therefore, in a very dark environment, the viewing distance of thermal imaging night vision devices is much longer than that of traditional night vision devices.
2. In harsh environments, thermal imaging night vision devices have obvious advantages
In foggy, rainy and other harsh environments, the observation distance of traditional night vision devices will be greatly reduced. But the impact on thermal imaging night vision devices will be minimal.
3. In environments with large changes in light intensity, thermal imaging night vision devices have obvious advantages.
We all know that traditional night vision devices are afraid of strong light, although many traditional night vision devices have strong light protection. However, if the ambient brightness changes greatly, it will have a great impact on the observation. But thermal imaging night vision devices will not be affected by light. It is for this reason that top-notch vehicle night vision devices, such as those on Mercedes-Benz and BMW, all use thermal imaging cameras.
4. In terms of target identification capabilities, traditional night vision devices have advantages over thermal imaging night vision devices.
The main purpose of thermal imaging night vision devices is to find targets and identify target categories, such as whether the target is a person or an animal. As for traditional night vision devices, if the clarity is enough, they can identify who the target is and can see the person's facial features clearly.
